Uninitialized constant error causes 500 server error with MailGun plugin

(Sander Datema) #1


  • anonymous user sends mail to group
  • someone from group replies
  • the anonymous user replies from another address
  • mail is bounced, but with a 500 server error

NameError (uninitialized constant Email::Receiver::UserNotSufficientTrustLevelError) /var/www/discourse/plugins/discourse-mailgun/plugin.rb:89:inhandle_failure’`

Of course this is an odd case. It happened because I tested something myself and then used the wrong from address. However, getting a 500 server error because of this is still an odd error.

Edit: I just noticed in that error that it’s the Mailgun plugin that I was using. So forget it. this is not a (confirmed) bug. @andreabedini, could you have a look?

Mailgun plugin for Discourse
Why was this title (see topic) not descriptive enough?

oh s****, people are using my plugin for real :astonished:. That part (around line 89) was copy and pasted, probably I left out some important part. If you have experience with RoR (I don’t have any actually), would you be able to figure out what’s missing?

It looks like the Discourse code (the error classes) changed here:

@zogstrip you probably want to check this out

(Simon Cossar) #5

I think the problem is that the old classes were being called from a plugin.

(Sander Datema) #6

Yep. :slight_smile: I was curious, so I tried it out.

(Andrea Bedini) #7

Yep, sounds like Discourse made come changes. To be honest I don’t have much interest in that plugin anymore. @Sander78 would you be interested in commit access to the github repo?

(Sander Datema) #8

I maybe would give it a go, but didn’t @sam mention somewhere that there’s an API for mails built in already? Can’t find any documentation on it though.

My understanding is that discourse handle email endpoint requires admin permission while mine is open to everyone. Of course one should check with it’s possible to get mailgun to pass a secret key or something, but I haven’t investigated it yet.

Same error @Sander78 has, using @andreabedini plugin, does somebody found a solution?

(Andrea Bedini) #11

Discourse made some changes back in Feb and the plugin is now broken. PR to fix it are well accepted. I am not using it anymore so it’s not supported.

I redirected e-mail to a Gmail address, then I uses pop3 to poll messages. It works well this way :slight_smile:
